NAME
Perl::Critic::Policy::Objects::ProhibitIndirectSyntax - Prohibit indirect object call syntax.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Indirect object syntax is commonly used in other object-oriented languages for instantiating objects. Perl allows this, but to say that it supports it may be going too far. Instead of writing my $foo = new Foo; it is preferable to write my $foo = Foo->new; The problem is that Perl needs to make a number of assumptions at compile time to disambiguate the first form, so it tends to be fragile and to produce hard-to-track-down bugs.
CONFIGURATION
Indirect object syntax is also hard for Perl::Critic to disambiguate, so this policy only checks certain subroutine calls. The names of the subroutines can be configured using the "forbid" configuration option: [Objects::ProhibitIndirectSyntax] forbid = create destroy The "new" subroutine is configured by default; any additional "forbid" values are in addition to "new".
CAVEATS
The general situation can not be handled via static analysis.
SEE ALSO
Perl::Critic::Policy::Dynamic::NoIndirect and indirect both do a better job with this, but they require that you compile/execute your code.
